Left: Gemini + Hokupa’a K‐band image of PKS 1830−211. This image shows a close‐up of the same data as in Fig. 1. Right: The simultaneous deconvolution of eight stacks of images allows a resolution of 0﹩\farcs﹩020 to be reached, sampled on a grid of pixels of 0﹩\farcs﹩010. The data, too shallow to reveal the lensing galaxies, is useful to measure the positions of the quasar images, with a very high precision. The pointlike object P (not modeled as a point source in the Gemini data) is clearly visible.
